Example Embodiment

[0025] As shown in the figure, the four-wheel drive tractor includes a front frame 5 and a rear frame 8, and a waist-bending steering mechanism 6 is provided between the front frame 5 and the rear frame 8. The waist folding steering mechanism 6 is composed of a waist folding knuckle 601 and a control system 602. The control system 602 includes a steering wheel 602a, a power transmission device 602b connected to the steering wheel 602a, and a driving device 602c connected to the power transmission device 602b. In an example, the power transmission device 602b is composed of a set of bevel gears and a set of worm gears. The turbine of the power transmission device 602b is connected with a driving device 602c to realize the twisting between the front frame 5 and the rear frame 8. In this embodiment, the driving device 602c is a rack and pinion driving device, wherein one end of the rack is hinged to the front frame 5. The front frame 5 is equipped with a power source 1 and a first...

Abstract

The invention discloses a four-wheel drive tractor which comprises a front frame, a rear frame, a first tail end assembly, a second tail end assembly, a front axle, and a rear axle, wherein a power source and a first speed changing box connected with the power source are arranged on the front frame; a second speed changing box is arranged on the rear frame; a bowing steering mechanism is arranged between the front frame and the rear frame; a transfer system and a differential mechanism are arranged inside the first speed changing box; the first tail end assembly is integrated on the first speed changing box; the second tail end assembly is integrated on the second speed reducing box, and the first speed changing box is connected with the second speed changing box through a power transfer shaft. The tractor is more flexible as the bowing steering mechanism is arranged between the front frame and the rear frame; the transfer system and the differential mechanism do not need to be arranged inside the tractor; a space inside the tractor is greatly saved; the speed changing boxes are compactly arranged, are small in volume and do not affect the steering operation; the tail end assemblies are integrated on the speed changing boxes, and the front axle is connected to the tail end assemblies, therefore, the space is saved.

Description

technical field [0001] The invention relates to a four-wheel drive tractor. Background technique [0002] The four-wheel drive tractor has excellent grip performance and large traction. Existing four-wheel drive tractors include a car body, on which a power source (gasoline engine or diesel engine) is arranged, the output shaft of the power source is connected to a gearbox, and the gearbox is connected to a transfer case, and the power obtained by the transfer case After the shunt, it is transmitted to the wheels through the differential, the terminal assembly, and the front axle (rear axle) in sequence. When the tractor needs to turn, by controlling the steering device of the front axle to deflect the front wheels at a certain angle, the tractor will rotate with the intersection of the axis extension lines of the front two wheels as the center of the circle. Its turning radius is big, and motion is inflexible, causes great difficulty to agricultural production. [0003] ...
